To travel on public transport in Stockholm, you will need to use an SL access card. The card can be purchased for 20 SEK and then loaded with money for single trips or with a ticket that is valid for a set period of time, for example 24 hrs, 48 hrs or 1 week. Stockholm's public transport system is split into three zones. Both ECDC and central Stockholm are located within zone A. More information on different ticketing options is available on the SL website. For timetables please use the SL journey planner.
